How to Read Casino Bonus Terms & Conditions: Wagering Requirements Explained
A big headline bonus number is easy to notice. The terms attached to it are what actually decide whether it’s worth claiming — and they’re where most of the disappointment in online casino bonuses comes from. Here’s what the key terms actually mean, so you can compare offers properly rather than just their size.
What Are Wagering Requirements?
A wagering requirement (sometimes called a rollover) is the amount you need to bet before you can withdraw winnings from a bonus. A “30x” wagering requirement on a £50 bonus means you’d need to wager £1,500 in total before that bonus money — or winnings from it — becomes withdrawable. The lower the multiplier, the more genuinely valuable the bonus is.
Minimum Odds and Qualifying Bets
Free bet offers on sportsbooks usually specify a minimum odds requirement (e.g. 1.5 or above) for both the qualifying bet and how the free bet itself can be used. Betting below that threshold typically won’t count toward unlocking or using the offer, so it’s worth checking before you place your qualifying bet, not after.
Game Weighting: Why Slots Count Differently to Table Games
Not every game contributes equally to a wagering requirement. Slots commonly count 100% toward it, while table games like blackjack or roulette are often weighted much lower (sometimes 10% or less), because they typically have a lower house edge. Playing the “wrong” games can mean grinding through a wagering requirement far more slowly than expected, or not at all.
Bonus Expiry and Withdrawal Caps
Bonuses usually expire after a set window — commonly between 7 and 30 days — so an offer with generous terms but a short expiry can still be harder to clear than a smaller offer with more time. Some bonuses also cap the maximum amount you can withdraw from winnings, regardless of how much you technically won.
A Quick Checklist Before You Opt In
- What’s the wagering requirement, and on what (bonus only, or bonus + deposit)?
- How long do you have to clear it?
- Which games count, and at what weighting?
- Is there a maximum withdrawal or conversion cap?
- Are there minimum odds requirements for free bets?
Every operator lays these terms out slightly differently, so it’s worth reading the full T&Cs on the specific offer rather than assuming. You’ll find licensing details and offer terms broken out on each of our full casino reviews.
